Hmmm, I have never actually had such an issue, and I got no idea what has actually caused this issue. I also hate it when something is smelling bad in the house, it just annoys me so freaking much! I actually think that you could try and change the soil, as it is the most common cause for this kind of issues. But are you sure that it is caused by the plants?! I would actually recommend you to call for the services of mymaid.co.nz
as they have got some of the best maids, and probably they would find the real cause of this smell.
